Heating, ventilation, and air conditioning (HVAC) systems play a critical role in determining indoor comfort and air quality in a home. There is more to the installation process than just setting up the new equipment. If you have been facing system inefficiencies, poor airflow, and low air quality, new appliances may not always fix the issues. Therefore, it's paramount to evaluate any underlying problems that may undermine the performance of new equipment. With this in mind, here are three services that HVAC companies can offer to improve system performance.
Test and Inspect Old Components
When installing new HVAC appliances in an existing home, you can reuse old components such as ductwork, thermostats, vents, and gas lines. Before pairing new equipment with older parts, your contractor should test and inspect the components for faults. For example, old, worn ducts may leak air and undermine the efficiency of your furnace or ducted AC. Failure to fix this problem will result in uneven heating and cooling, even after investing in a new system.
Similarly, if you installed thermostats in the wrong location, they may provide inaccurate readings, leading to efficiency issues. For example, a thermostat installed in the path of direct sunlight will record false readings and cause your new system to cycle on and off frequently. Inspect existing components and look out for any wear, damage, or installation errors that may affect the new system's efficiency.
Address Airflow Issues
Airflow issues can cause hot and cold spots, pressure imbalances, and inadequate heating and cooling. Minor causes of airflow issues include worn or dirty filters, clogged ducts, low refrigerant, and an obstructed condenser unit. Most of these problems usually go away when you install new heating and cooling systems. However, airflow issues can also stem from poor sizing of the ductwork.
The size of your ducts determines the amount of air that can pass through at once. If you have small ducts in a room with a high heating and cooling demand, the airflow may be inadequate. Buying a larger furnace or split AC unit won't solve the airflow issues. Therefore, your contractor should check your ductwork to ensure proper airflow and pressure balance. Replace improperly sized ductwork to enhance the performance of the new HVAC system.
Evaluate Overall Performance
The efficiency of an HVAC system doesn't rely solely on the equipment. Factors such as air sealing and insulation can affect indoor comfort. For example, a poorly insulated home will still lose warm or conditioned air through the floors, walls, windows, and roofing. Therefore, new HVAC equipment may do little to enhance indoor comfort. When installing the new system, your contractor should look around your home and recommend ways to improve comfort and energy efficiency.
